Accessing LDAP with Java to verify User/Password

Hi,

i would like to access the Portal-LDAP without using the EP. The idea is to use the same user information as in the Portal in another standalone application which has no web interface (not a http application).

Are there any java-packages in the EP-Installation i can use for that? If yes which are they and do they need any configuration files? Or is it the easiest to access the LDAP by using the standard java JNDI way?

All i need to do is to check the User-ID with the password and to retrieve the roles.

Has anybody done the same?

Regards

Stefan
